umns may be *builty rapidly byuse of yslip i forms,.and a suitable insulation of the entire wall, including the columns, may be provided.

An understanding of the inventionV may be had most readily by reference to the examples of construction and apparatus shown in the l drawing. `In' Fig. 1 is shown 'a double wall construction in which the. inner concrete-wall 10 andouter concrete wall 1lv are spaced apart by an intervening insulation space 12. At intervals in thewall are formed columns, made vby increasing ythe thickness of the wallsat Vthesev points, said columns constituting streng'tl'ienimgYand stiffening members inthe Wall and affording supportfor the floors 50.

As seen 'in detail ofFig; 4, to form a column, the innergwall-is formed witha thickened por- -v -tlionor p ilaster il()a which projects part way;

across the air space 12, and the wall 11 is formed with a similar thickenedk portion or pilaster 11a aligning withthe portion 10a, and an insulating slab 16 is'interposed and bonded between the walls withinthe area of the column, the portions of the column which are integral with the respective walls being tied together by tie rods 17. 'lhus columns may be formed wherever desired in the wall and at the corners of the building. Y

In Figs; 3 and l are illustrated certain features of the slip forms whereby a wall of such construction may be eiected. 'These `slip forms are similarto those familiar inthe art in lia-ving a number; of elevatingframes at intervals alongthe wall, and carrying the handling platforms or runways 20 vandthe jack screws 21 whereby the frames andthe portions carried thereby may be elevated from time to time on the jack rods 22 which extend vertically in the wall.v These frames carry theouter form panels 24: and the inner form panels'25 and the intermediateform panels 26. The outer and inner form panels are arranged to constitute continuous mold surfaces delining the outer and inner-surface limits of the wall, but the intermediateV form panels are spacedapart at intervals to allow gaps of the widthsand in the locationsv desired for the col-l umns. The intermediateform panels 26 are ,spaced in thetransverse dire'ctionof the wall by such a distance as to form theinsulating Vspace '12 of the desired width, the.V space between the panels being closed at the endsthereof by end` plates 27. `.Opposite these gaps between aligning sections of the intermediate panels, the outer panel is formed with out-set vportions 24a,vcontinuity of the sameand theY portions 24 being' maintained by the joining strips 24". The various panels are maintained inparallel relationship"vertically, the outer panel being supported by the vsuspension rods 28 and retained by the adjacent ver# tical frame members 18, the inner panel being supported by suspensionrods 29 and retained by the other vertical framememb'erslS, and the intermediate panels being supported by the suspension means 8O and retained bythe frame members 19. Y .y

. 1n the construction ofY a building, ordinarily the slipV forms will extendtheV full length of awall, or around the` entire eX- tent of the enclosing wallsof the entire building. The relationship of the form panels, as above described, forms a mold-into which the fluid concrete is poured; and allowed to set, suitable reinforcement-rods beingdisposedin vthe mold cavity inthe desired locations, and firiollng the inner Surfggs of thawall, Said theforms beingraised from time toy time to 'extend the mold cavity fup'wardly ,from the 'portionsof the wall already poured, to receive the additionalpourings, this being the customary procedure in the operation of slip forms. The concrete, of course, is suitably distributed in the moldcavities, so as to take a monolithic bond between the outer wall 11 l and the inner wall 10. v 1n the present invention, however, this is supplemented by the intei'posing of insulating slabs 16 across these gaps. These slabs may be of cork, and they v are of suitable widthV to ymake contact'with the/end plates 27 of the spaced intermediate panel sections, and are of suitable thickness to have the desiredinsulating effectin- They kare rmaintained in .position by guides 81 carfornied of vvertical jmembers 18 and transverse members 19, said frames being disposedried' on the form frames in Vposition to main- 4'talinrthe slabs with one surface in alignment with the mold face ofthe outer side of the v intermediate panels and the other surface outset from the mold face of theother intermediate'panel. Thus] the"insulating slab vforms partv ofthe mold face for the inner surface of the outer wall 11, andthe mold tending reinforcing rods 32, placedin the respective wall portions opposite the gap, are

tiedvacrossby the tie members' 17 between ends of superimposed insulating slabs. vAs the vforms are elevated, these slabs remain in place in the columns, forming a structural portion thereof aswell asinsulating inserts. rlhe floors'l, which are subsequently poured, are bracketed into the column portionsof'the inner wall. vThe air'spaces '12 between the walls maybe left void, or filled with insulating material.` 1f desired, insteadof running the'insula'tingjslabscontinuously, spaces may be left between thev ends of the successive slabsxtop'ermit integra-l concrete bonds to be formed between the inner and outerV wall portions at intervals. n e v f n VFrom the foregoing explanation, 4itwill beV seen that byemploymentof the invenf tions .herein described, [double monolithic concrete walls may beV formed with columns which are insulated ,within thearea of the wall vand havingthe strength necessary to carry the floors and to sustain intermediate wall portions'of reducedI thickness vand that the erectionof suchv walls may be carried on rapidly, lby employment 'of slip forms and witlrthe resulting savinggin' labor and mate'- rial costs.
